Wind Simulation & Wind Load Generation

With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.

The generated wind loads acting on these objects can be imported to RFEM or RSTAB.

  1. Structural System

    Calculating Timber Panel Walls | 2. Stiffness and Slip of a Wall

    The calculation of timber panels is carried out on simplified member or surface structures. This article describes how to determine the required stiffness.

  2. RFEM Model

    Timber Beam Design per the 2018 NDS Standard

    Using the RF-TIMBER AWC module, timber beam design is possible according to the 2018 NDS standard ASD method. Accurately calculating timber member bending capacity and adjustment factors is important for safety considerations and design. The following article will verify the maximum critical buckling in RF-TIMBER AWC using step-by-step analytical equations per the NDS 2018 standard including the bending adjustment factors, adjusted bending design value, and final design ratio.

  3. Timber Panel Construction

    Calculating Timber Panel Walls | 1. Determining the Ultimate Limit State and Stiffness

    The stiffening of timber structures is usually carried out by means of timber panels. For this purpose, structural components consisting of slabs (chipboards, OSB) are connected with members. Several articles will describe the basics of this construction method and the calculation in the RFEM program. This first article describes the basic determination of the stiffnesses as well as the calculation.

  4. Influence of the Load Duration on the Design Value of the Strength

    Load Combinations in Timber Structures for European and American Timber Standards

    In addition to determine loads, there are some particularities concerning the load combinatorics in timber design which have to be considered. Contrary to steel structures where the largest loading results from all unfavorable actions, in timber construction, the strength values are dependent on the load duration and the timber humidity. Special characteristics have to be considered as well for the serviceability limit state design. The following article discusses the effects on the design of wooden elements and how this is possible with RSTAB and RFEM.

  5. Structural System and Cross-Section Dimension According to [1]

    Modeling of Semi-Rigid Composite Beam Made of Timber as Surface Model

    There are several options to calculate a semi-rigid composite beam. They differ primarily in the type of modeling. Whereas the Gamma method ensures a simple modeling, additional efforts are required when using other methods (e.g. shear analogy) for the modeling which are, however, offset by the much more flexible application compared to the Gamma method.
  6. Figure 01 - Modeling Curved Beams

    Design of Curved Glulam Beams According to ANSI/AWC NDS

    RFEM offers the possibility to model also curved beams. To do this, a curved line must be created first (see Figure 01).This line can then be assigned a beam with a cross-section. The advantages over modeling with beam segments are the easier handling during the modeling as well as the clearer results output of the internal forces.

  7. Design of Notches and Cross-Section Reductions in TIMBER Add-on Modules

    Design of Notches and Cross-Section Reductions in Timber Add-on Modules

    As of the program version X.06 of the add‑on modules RF‑/TIMBER Pro, RF‑/TIMBER AWC and RF‑/TIMBER CSA, it is possible to consider notches and cross‑section reductions in the design. The procedure is as follows.

  8. SLS Checks Taking into Account the Resulting Deformation

    SLS Checks Taking into Account Resulting Deformation

    In the add‑on modules RF‑/TIMBER Pro, RF‑/TIMBER AWC, and RF‑/TIMBER CSA, you can now take into account the resulting deformation of a member or set of members. In addition to the local directions y and z, you also have the option “R.” This allows you to compare the total deflection of a girder to the limit values given in the standards.
